Signal connection of a terminal block for the multichannel I/O module
The signal cables of the field devices to the terminal blocks for the multi-channel I/O module must
be connected to different terminals depending on the types of signals. To prevent damage to
devices, connect signal cables to the appropriate terminals according to the type of signals.
The following table shows the relationship between signal types and terminal numbers of
channels.
